I think another good one would be Mr. Dolphus Raymond. Before really meeting him, the kids think he's just a town drunk who lives in sin with his black wife and mixed kids. When they actually meet him, they realize that he's just a nice guy who wants to live his life in peace...drinking coke out of a bottle in a plastic bag. Scout understands that he does that because that's what people would "expect" or rather "accept." She realizes he's just happy living his life with his family and not being bothered with the ideas and criticisims of the rest of the community. He'd rather people focus on him being a "drunk" than giving their own analysis for his happy life.
That's a good list, so I'll just add to it.
Scout sees things from Walter Cunningham's perspective when Miss Caroline tries to give him lunch money. She understands that the Cunninghams won't take what they can't repay. When he comes to share the noon meal with them, she is awed that he and Atticus can carry on such an adult conversation about things she doesn't understand at all. (This doesn't keep her from being rude to her invited guest, though.)
Scout, at the very end of the story, sees things from Boo Radley's perspective. The conversation Atticus and Heck Tate have is fairly veiled as they're arguing about letting the town know it was Boo who killed Bob Ewell. When her father asks her if she understands, Scout remarks that it'd be just like killing a mockingbird. She understands Boo's wish--need, even--to be kept out of the public eye and speculation.
Scout and Jem both have a fresh perspective on the cranky old woman they used to be afraid of--Mrs. Henry Lafayette Dubose. While they didn't see things from her point of view until it was too late and Mrs. Dubose had died, they did have a new appreciation for the courage it must have taken to overcome such an addiction.
Certainly they both got a new perspective on living a bi-racial existence in a segregated South from their short encounter with Dolphus Raymond. From him they saw that race is not a determining factor for human relationships, as well as the mindless prejudice of a town who needed to find some other excuse to justify its intolerance.
Keep looking, as there are undoubtedly more; nearly everyone in this novel teaches the kids--and Scout in particular--to see things from another perspective. (How about Lula at Cal's church who hates them because they're white; or Mr. Underwood who has no love for blacks but is awfully intolerant of unfair treatment; or Mayella Ewell who is just lonely and wants a friend--any friend.) Those two years, and particularly that summer, were certainly growing times for the young Scout.
Scout has multiple opportunities throughout the book to see things from other perspectives. It starts, of course, on the first day of school with Miss Caroline. Her next opportunity is when Walter Cunningham comes home for supper and she is scolded by Cal for picking on him with the molasses. The rest are not in chronological order, but here goes...
She sees things from Cal's perspective when she attends church with her one Sunday. She sees things from the Robinson's perspective (and other black people) first when she sits in the balcony at the court and next when she accompanies Atticus to give Helen the news of Tom's death.
She sees things from Miss Maudie's perspective on the day of the missionary tea and this is an opportunity to gain understanding into Aunt Alexandra (which Scout probably misses). The mob scene gives her an opportunity to see things from Atticus' perspective, as well as Mr. Cunningham, for a moment. Finally, at the end of the book, she walks down the street and sees things, for the first time, from Boo Radley's perspective.
